I stumbled across this post which describes how you can embed slides into your website. If you use either a free Flickr account (or Google’s Picasa), you can export your Powerpoint slides as image files, upload them to your photo site, and then insert a bit of code to embed your slides. It takes a few minutes, but it is certainly a useful little hack. Hopefully Flickr (and Picasa) won’t change their code to beat this hack.
Obviously the example shown below is not too pretty because my content space does not have a lot of width. I’ve noticed that this alters Flickr’s functionality a bit. One other note – be sure that you upload your slides in reverse chronoligical order so that your first slide is the one most recently uploaded. Unfortunately, I cannot seem to find a way to change the slide order.
